Ericsson has filed a patent suit against Samsung in the US alleging that the Korean firm has refused to renew a licence to use some of its technology on the same terms other companies have accepted.

The Swedish firm must have been feeling left out of the Great Patent Wars, because it filed two suits against Sammy in Texas, one with 11 patents and the other with 13.

"Despite nearly two years of negotiations involving the most senior management of both companies, Samsung has refused to renew its expired licence to Ericsson's industry leading portfolio of telecommunication patents on the same fair, reasonable and non-discriminatory terms that Samsung’s competitors have previously accepted," the firm said in its court filing.

The telecoms equipment manufacturer wants the usual battery of awards from the court, including damages for recompensation and more damages because Samsung is doing this on purpose and, of course, the inevitable injunctions.

Ericsson is citing a whole host of Samsung gear, including mobiles, tablets, base stations and any other devices with wireless capabilities. ®
